Novel ferrocene derivatives, surfactants containing same and process for producing organic thin films

Abstract

A ferrocene compound represented by the formula: ##STR1## wherein R 1 and R 2 are identical or different and are a hydrogen, a methyl group, a methoxyl group, an amino group, a dimethylamino group, a hydroxyl group or a halogen, X is ##STR2## Y is ##STR3## M is an alkali metal or an alkaline earth metal, a is an integer of 1 to 4, b is an integer of 1 to 5, k is an integer of 1 to 18 and m is an integer of 0 to 4. The ferrocene compound can be used as a surfactant to produce an organic thin film from various hydrophobic organic substances. The surfactant serves to make the hydrophobic organic substance soluble in an aqueous medium.
